JOSEPH HENRY HAMPSON, OF KANSAS CITY. MISSOURI.

FLANGE AND ICE-CUTTER FOR RAILWAY-CARS.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed August 21.1906. Serial No. 331,447.

To all whom it may concern:

Be it known that I, JOSEPH HENRY HAMPSON, a citizen of the United States, residing in Kansas City,

7 county of Jackson, State of Missouri, have invented a certain new and useful Flange and Ice-Cutter for Railway-Cars, of which the following is a specification.

The object of my invention is to secure safety and economy in the operation of railways in countries where snow, ice or sleet forms on the tracks. This object I accomplish by providing car wheels withmy flange and ice-cutter.

The advantage of this construction will more particularly appear if reference be had to the accompanying drawings which illustrate my invention.

Figure 1 shows a plan view of a car wheel, provided on its inner periphery with a toothed flange; Fig. 2 is a side elevation of the wheel; Fig. 3 shows the toothed flange enlarged; Fig. 4 shows the toothed flanged wheels attached to trucks of a railway car and resting on the tracks.

The simplicity of the device requires but few additional words of explanation.

' A. is the wheel; B. represents the toothed flange.

It will be readily seen that if a locomotive, either steam or electric, or motor cars are constructed with this device, the ice-cutter will clear away ice and sleet from the rails and thus greatly reduce the friction of the cars of the train which follow.

A still further advantage of this contrivance is that it clears the ice in switches.

The efliciency of this structure will at once be recognized if it be recollected that the standard thirtysix inch wheel revolving at a speed of sixty miles per hour, making five hundred and eighty revolutions to the minute causes the cutter to act like a fast revolving circular saw. The cutter, however, will perform its function at any rate of speed. It can also be manufactiu'ed and adapted to any class of wheels and to any kind of rail, and particularly to grooved rails.

An additional advantage which it possesses over and above all other forms of devices constructed to accomplish similar purposes is that the cutter will not remove torpedoes without exploding them, nor interfere with torpedoes placed on the tracks to warn approaching trains, except as desired,

It should also be understood that the tooth of my flanged wheel may be cast at any angle.

Having thus described my invention, what I claim is:

1. In combination with a railway car or locomotive, wheels of said car or locomotive having a toothed flange integral with said wheels adapted and constructed to cut ice formations from an ordinary grooved or flat rail, substantially as described.

2. In a railway car or locomotive, the combination of two or more wheels of said car or locomotive having toothed flanges on said wheels adapted and constructed to cut'ice formations from an ordinary grooved or flat rail.

3. In a railway car or locomotive, the combination of one or more wheels of said car or locomotive and flanges on said wheels integral with said wheels on their inner peripheries, and adapted and constructed to cut ice formations from grooved or fiat rails over which said vehicle passes, substantially as described.

In witness whereof, I have hereunto set my hand this thirteenth day of August, 1906.
